Pattern of socio-economic and health aspects among TB patients and controls

Background Socio-economic and health-related factors have a significant impact on tuberculosis (TB) incidence among population residing in resource-scare settings. Objective To evaluate the pattern of socio-economic and health-related factors among TB patients and control in Delhi, India. Methods The present cross-sectional study was performed among 893 TB patients (or cases) and 333 healthy disease-free controls. The data for the present study was obtained from several district TB centres in north, west and south Delhi. The collected data was edited, coded and statistical analysed with the help of SPSS 20.0 version. Results Illiteracy and primary education were significant risk factors being associated with a TB. Rented housing condition had an odds ratio (OR) of 1.4 (95% confidence interval [CI]: 1.09–1.89) compared to owned housing condition. 3–5 individuals per room were 3 times more likely to be associated with a case of TB (95% CI: 2.49–4.41). Migrant individuals were 13 times more likely to be associated with a case of TB (95% CI: 8.77–19.78) in comparison to settled population. Daily consumption of non-vegetarian food also significantly contributed to case of TB with an OR of 3.4 (95% CI: 2.51–4.72). Loss of appetite and family TB served as significant health-related factors associated with TB risk. Conclusion Lower educational status, rented household, individuals per room (as a measure of overcrowding) and migratory status served as prominent risk factors for TB disease. Preference and frequency of non-vegetarian food being consumed, night sweating, weight loss, loss of appetite, earlier TB and family TB were principle health-related risk factors associated with TB disease.
